4-M,M'-Di-t-butyl-p-hydroxyphenyl) butyl-2 compounds

Abstract

Novel 4-(m,m'-di-t-butyl-p-hydroxyphenyl)-butyl-2 compounds which are intermediates in the manufacture of dyes, pesticides and plastics auxiliaries, particularly stabilizers for polyolefins and polyamides. When molten, they form specific solvents for alkylphenols and are perfumes or form ingredients of perfume compositions having a fruity odor.

We claim: 
     
       1. 4-(m,m'-di-t-butyl-p-hydroxyphenyl)-butyl-2-amides of the formula: ##STR25## in which the radicals R 1  are the same or different and each individually is hydrogen or an aliphatic radical, and R 3  denotes an aliphatic, cycloaliphatic, araliphatic or aromatic radical. 
     
     
       2. Compounds as claimed in claim 1, in which the radicals R 1  respectively are hydrogen or alkyl of 1 to 4 carbon atoms, R 3  is alkyl of from 1 to 20 carbon atoms, cyclohexyl, aralkyl of from 7 to 12 carbon atoms, naphthyl or phenyl, which radicals of R 1  and R 3  may be further substituted by alkyl or alkoxy of from 1 to 4 carbon atoms or by nitro. 
     
     
       3. Compounds as claimed in claim 1 in which each R 1  is hydrogen, and R 3  is alkyl of 1 to 20 carbon atoms. 
     
     
       4. Compounds as claimed in claim 1 in which each R 1  is hydrogen, and R 3  is phenyl. 
     
     
       5. A compound as claimed in claim 1, said compound having the formula ##STR26## 
     
     
       6. A compound as claimed in claim 1, said compound having the formula ##STR27## 
     
     
       7. A compound as claimed in claim 1, said compound having the formula ##STR28##
